Description

Whether you're heading into a tough training session, powering through your daily routine, or recovering from activity, HYDRO+ helps you stay on top of your hydration. Each serving contains 1576mg of electrolytes, plus Vitamin C for immune and energy support, and vitamins B6 and B12 to reduce fatigue, all in a light, refreshing drink that mixes easily into 500ml of water.

The inclusion of these vitamins makes HYDRO+ more than just a hydration product. It works to support energy metabolism, reduce tiredness, and help you recover faster, especially when training intensifies or when you’re exposed to high temperatures. Thanks to the handy sachets, it’s easy to carry and use, whether you’re at the gym, on a run, or travelling.

Scientifically developed by SiS, HYDRO+ meets the needs of endurance athletes, gym-goers, and busy individuals alike. It delivers an optimal blend of minerals and vitamins to help you stay hydrated, energised, and ready to perform, whenever and wherever you need it.

How does it work

HYDRO+ works by replenishing vital electrolytes and supporting hydration, especially when sweat loss is high during exercise or warm conditions. These electrolytes are essential for muscle contraction, nerve function, and maintaining fluid balance. Without them, performance can drop and fatigue can set in quickly.

Alongside the minerals, Vitamin C helps support your immune system and energy metabolism, while B6 and B12 help reduce tiredness and support red blood cell production. Together, these nutrients help you stay alert, hydrated, and physically ready for whatever your day throws at you.
